sort( $new, SORT_NATURAL | SORT_FLAG_CASE );
SORT_NATURAL is new in php 5.4 but i have 5.3.10 running on my localhost (ubuntu 12.04) not really intention to upgrade because of that.
What would be the equivalent in php 5.3, i have read that is just like natsort.
is natsort( $new, SORT_FLAG_CASE ); the same ?
The PHP Manual points out that natsort ($array) is the equivalent of sort($array,SORT_NATURAL); it also points that SORT_FLAG_CASE wasn’t added until 5.4.0 either.
You can use natcasesort($array) which is the equivalent of sort($array,SORT_NATURAL | SORT_FLAG_CASE).
Answer：
While they are essentially the same, the important difference to note between natsort($array) and sort($array, SORT_NATURAL) is key associations.
natsort() maintains key associations, meaning that keys and values are kept linked.
However, sort() does NOT main associations, so values are reassigned keys based on their new order.
